Description

Technical Field

[0001] The invention belongs to the technical field of roofing, and in particular relates to a waterproof roof and a construction method thereof. Background Art

[0002] The roof panels of factories and warehouses are often assembled from modular corrugated panels, with a waterproof layer applied above the panels to prevent water leakage at the joints. Currently, the assembled corrugated panels are often secured to the keel with self-tapping screws. These screws penetrate the panels. While the upper waterproof layer is normally waterproof, if it breaks, water can seep into the interior through the holes penetrated by the self-tapping screws. Furthermore, the exposed waterproof layer is easily damaged by wind and sun, and the protrusions of the self-tapping screws prevent the waterproof layer from fitting tightly against the panels, further increasing the risk of damage. Furthermore, the joints of the corrugated panels are fragile and prone to deformation and fracture when subjected to external forces, such as compression or collision. This not only limits the roof's service life but also increases the risk of damage to the waterproof layer. Furthermore, due to the limited thickness of the corrugated panels, they are prone to deformation during production, transportation, and installation, making it difficult to ensure a tight fit during splicing, and gaps can easily form at the joints. Furthermore, most current roofs use a single-layer structure, which is relatively weak and provides poor insulation.

[0003] The invention patent with publication number CN114961124A discloses a hollow double-layer waterproof roof and its construction method, comprising a first metal plate, the right side of the first metal plate and the left side of the second metal plate being mutually clamped, the left sides of the first metal plate and the second metal plate being fixedly connected with a positioning block, the right sides of the first metal plate and the second metal plate being both provided with a positioning groove, the inner walls of the mutually adjacent positioning grooves being overlapped with the outer surfaces of the positioning blocks. By providing an auxiliary support layer, a filling layer, a waterproof isolation layer, a reinforcement layer and a thermal insulation layer, the possibility of deformation of the irregular grooves is reduced, thereby ensuring the waterproof effect of the waterproof roof, and the addition of a hollow foam board improves the strength of the waterproof roof, avoiding the damage and deformation of the waterproof roof when subjected to external force collision, thereby ensuring the service life of the waterproof roof. However, although it adopts a double-layer structure and is provided with an auxiliary support layer and a filling layer to improve the strength of the roof, the first metal plate and the second metal plate are fixed by positioning screws passing through the through holes. Water can still penetrate to the bottom through the through holes, and its installation and positioning structure is complicated, which is not conducive to construction. Summary of the Invention

[0015] Through the above technical solution, the beneficial effects of the present invention are: 1. The present invention provides two layers of protection by arranging the upper roof panel group and the lower roof panel group at intervals, which can ensure the waterproof effect and have good thermal insulation performance. The upper roof panel group and the lower roof panel group are respectively pressed against the upper top beam and the bottom beam by tightening the assembly, and no bolts are required to penetrate and fix them, which is convenient for on-site construction and avoids water seepage from the penetration points. In addition, the upper and lower surfaces of the upper roof panel group and the lower roof panel group are relatively flat, and the waterproof layer can be reliably attached to the upper roof panel group or the lower roof panel group. The waterproof layer is not easily damaged. At least one waterproof layer is located on the inner side of the roof to protect the waterproof layer from wind and sun, thereby increasing the service life of the waterproof layer and further avoiding damage to the waterproof layer, thereby improving the waterproof performance of the roof.

[0016] 2. The present invention tightens the longitudinal support plates and diagonal support plates of the assembly to the joints of the corrugated plates. While positioning and fixing the upper roof panel group and the lower roof panel group, the external force is used to force the joints of the corrugated plates to fit tightly together. Even if the corrugated plates are slightly deformed during production or transportation, it will not affect installation and use, further ensuring the waterproof and thermal insulation properties.

[0017] 3. The present invention is provided with longitudinal support plates and diagonal support plates, which are controlled by adjusting the axial movement and rotation of the shaft in sections. This is not only convenient for construction, but also avoids double positioning when an integral positioning structure is used, which causes gaps at the top or side of the overlap. It is more suitable for corrugated plates with deformation and ensures reliable sealing of the overlap of the corrugated plates. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] Example 1 Currently, most metal roofs are single-layer structures, with the assembled corrugated panels secured to the keel with self-tapping screws, followed by the application of a waterproof layer. Self-tapping screws penetrate the corrugated panels, and while the upper waterproof layer is normally waterproof, if the waterproof layer breaks, water can seep into the room through the holes penetrated by the self-tapping screws. The exposed waterproof layer is easily damaged by wind and sun, and the protrusions of the self-tapping screws prevent the waterproof layer from fitting tightly against the corrugated panels, further damaging the waterproof layer. Furthermore, the joints of the corrugated panels are relatively fragile and prone to deformation and fracture when subjected to external forces, squeezing, or collisions. This not only limits the roof's service life but also makes the waterproof layer more susceptible to damage.

[0022] See also Figures 1 to 6 A first embodiment of the present invention provides a waterproof roof, including a keel support and a corrugated plate, the corrugated plate including staggered peak sections and valley sections, the keel support including an upper top beam 1 and a bottom beam 2, the number of the upper top beams 1 and the number of the bottom beams 2 are five and are arranged parallel to each other at intervals, the upper top beam 1 is located directly above the bottom beam 2, the number of the upper top beams 1 and the number of the bottom beams 2 are equal and are arranged one-to-one, an upper roof panel group 6 is laid on the lower side of the upper top beam 1, and a lower roof panel group 7 is laid on the upper side of the bottom beam 2; a waterproof layer 8 is laid on the upper or lower side of the upper roof panel group 6 and the upper side of the lower roof panel group 7.

[0023] A tightening assembly is provided between the upper top beam 1 and the bottom beam 2. The upper end of the tightening assembly pushes the upper roof panel group 6 together with the waterproof layer 8 on the upper roof panel group 6 to the upper top beam 1, and the lower end of the tightening assembly pushes the lower roof panel group 7 together with the waterproof layer 8 on the lower roof panel group 7 to the bottom beam 2.

[0024] When the waterproof layer 8 of the upper roof panel group 6 is laid on its upper side, construction is convenient; when the waterproof layer 8 of the upper roof panel group 6 is laid on its lower side, the upper roof panel group 6 needs to be lifted when pasting and laying the waterproof layer 8, so that the waterproof layer 8 passes through the lower top beam 3, but the waterproof layer 8 is located on the inner side of the roof, which can increase the service life of the waterproof layer 8.

[0025] The waterproof layer 8 is a thermoplastic polyolefin waterproof membrane. After the waterproof layer 8 is laid on the upper roof panel group 6 or the lower roof panel group 7, the waterproof layer 8 is heated by a flame spray gun to make the waterproof layer 8 adhere to the corrugated board.

[0026] In this embodiment, the peak section of the corrugated plate in the upper roof panel group 6 and the peak and valley section of the corrugated plate in the lower roof panel group 7 are longitudinally mirrored, the peak sections of two adjacent corrugated plates in the upper roof panel group 6 are longitudinally overlapped, and the peak and valley sections of two adjacent corrugated plates in the lower roof panel group 7 are longitudinally overlapped, and the overlapping part of the upper roof panel group 6 is located directly above the overlapping part of the lower roof panel group 7.

[0027] The bracing components are located at the overlap of the upper roof panel group 6 or the lower roof panel group 7 and at the side of the upper roof panel group 6 or the lower roof panel group 7.

[0028] In order to facilitate the splicing of the upper roof panel group 6, the keel bracket also includes a lower top beam 3, a side panel 4 and an end panel 5. The lower top beam 3 is located below the upper top beam 1 and is horizontally staggered with the upper top beam 1. The distance between the lower top beam 3 and the upper top beam 1 is greater than the height of the corrugated plate. The two side panels 4 and the two end panels 5 form a U-shape. The upper top beam 1, the lower top beam 3 and the bottom beam 2 are fixedly arranged between the two side panels 4. The sides of the upper roof panel group 6 and the lower roof panel group 7 are attached to the side panels 4. The tightening assembly is arranged between the two end panels 5, and the ends of the upper roof panel group 6 and the lower roof panel group 7 are attached to the end panels 5; when splicing the upper roof panel group 6, the corrugated plate is placed on the lower top beam 3 for easy positioning during splicing.

[0029] In order to facilitate the replacement of the corrugated plate during maintenance, the end plate 5 includes an upper plate 501, a middle plate 502 and a lower plate 503 arranged in sequence from top to bottom. The height of the top surface of the middle plate 502 is not higher than the height of the top surface of the lower top beam 3. The distance between the bottom surface of the middle plate 502 and the top surface of the bottom beam 2 is greater than the height value of the lower roof panel group 7. A through hole is opened on the side of the upper plate 501 to prevent water accumulation on the upper roof panel group 6.

[0030] In summary, by spacing the upper and lower roof panels 6 and 7, two layers of protection are provided, ensuring a waterproof effect while also providing good thermal insulation performance. The upper and lower roof panels 6 and 7 are respectively supported against the upper top beam 1 and bottom beam 2 by tightening the assembly, eliminating the need for bolt penetration and fastening, facilitating on-site construction and preventing water seepage from the penetrations. Furthermore, the upper and lower surfaces of the upper and lower roof panels 6 and 7 are relatively flat, allowing the waterproof layer 8 to reliably adhere to the upper and lower roof panels 6 and 7, making the waterproof layer 8 less susceptible to damage. At least one waterproof layer 8 is located on the inside of the roof, protecting the waterproof layer 8 from wind and sun, increasing its service life, and further preventing damage to the waterproof layer 8, thereby improving the waterproof performance of the roof.

[0031] Example 2 In the above-mentioned embodiment, the bracing assembly merely secures the upper and lower roof panels 6 and 7 within the keel brackets. However, the corrugated panels are relatively fragile at their joints and are prone to deformation and fracture when subjected to external forces, which not only limits the roof's service life but can also puncture the waterproof layer at these fractures. Furthermore, due to their limited thickness, the corrugated panels are susceptible to deformation during production, transportation, and installation, making it difficult to ensure a tight fit during splicing, and gaps are likely to form at the joints. To address these issues, further improvements have been made to the above-mentioned embodiment.

[0032] See also Figure 7-12 The tightening assembly includes a positioning tube 9, an adjusting shaft 10, and a longitudinal tightening mechanism. The positioning tube 9 is fixedly arranged in the keel bracket. The two ends of the positioning tube 9 are fixedly fitted on the two middle plates 502. The positioning tube 9 is arranged along the length direction of the corrugated plate and is located between the upper roof panel group 6 and the lower roof panel group 7. The adjusting shaft 10 is slidably fitted in the positioning tube 9. The five longitudinal tightening mechanisms are arranged at intervals along the length direction of the tightening assembly.

[0033] The longitudinal tightening mechanism includes a rotating sleeve 17 and two longitudinal tightening parts arranged in a longitudinal mirror image. The rotating sleeve 17 rotates and fits on the regulating shaft 10 and slides axially on the positioning tube 9. The longitudinal tightening part includes a longitudinal support plate 11, two first support rods 12 and a second support rod 13. The longitudinal support plate 11 is laterally arranged on the upper or lower side of the positioning tube 9. There are two first support rods 12 arranged in parallel. The inner end of the first support rod 12 is hinged to the rotating sleeve 17, and the outer end of the first support rod 12 passes outward through the positioning tube 9 and is hinged to the longitudinal support plate 11. The inner end of the second support rod 13 is hinged to the positioning tube 9, and the outer end of the second support rod 13 is hinged to the middle part of the adjacent first support rod 12.

[0034] The second support rod 13 forms a triangle with the first support rod 12 and the positioning tube 9, and the stable structure of the triangle provides reliable support force for the longitudinal support plate 11; the first support rod 12, a second support rod 13, the longitudinal support plate 11 and the positioning tube 9 form a parallelogram connecting rod structure, and the longitudinal support plate 11 maintains a horizontal state during the lifting process, so that it can better fit the corrugated plate. When the regulating shaft 10 slides axially along the positioning tube 9, the regulating shaft 10 drives the longitudinal support plates 11 of the two longitudinal tightening parts to rise and fall synchronously in the opposite direction.

[0035] Both ends of the regulating shaft 10 extend outward from the positioning tube 9, and both are threaded with nuts. The two nuts are rotated to make the end faces of the nut fit and lock with the end faces of the positioning tube 9. After locking, the relative position of the regulating shaft 10 and the positioning tube 9 can be maintained, so that the tightening assembly is always in a tightened state.

[0036] A convex ring is fixed on the regulating shaft 10, and the rotating sleeve 17 is located between the two spaced convex rings. The convex ring drives the rotating sleeve 17 to move axially along the regulating shaft 10. A sliding groove is opened on the circumferential side wall of the positioning tube 9 along its length direction, and the rotating sleeve 17 slides into the sliding groove along the length direction of the sliding groove.

[0037] The tightening assembly also includes a transverse tightening mechanism, and five transverse tightening mechanisms are arranged at intervals along the length direction of the tightening assembly; the transverse tightening mechanism includes a transverse support plate 14, a cam segment 15 and an oblique support plate 16. The longitudinal section of the transverse support plate 14 is ├-shaped, and the horizontal section of the transverse support plate 14 is laterally slidably arranged on the positioning tube 9. The transverse support plate 14 is two transverse mirror-imaged. The two transverse support plates 14 are respectively located on both sides of the positioning tube 9, and the cam segment 15 is coaxially arranged with the regulating shaft 10 and integrally formed. The longitudinal section of the cam segment 15 is elliptical, and the horizontal section end of the transverse support plate 14 abuts against the side wall of the cam segment 15. The two oblique support plates 16 are respectively arranged at the upper and lower ends of the vertical section of the transverse support plate 14. The middle part of the oblique support plate 16 is hinged to the upper or lower end of the vertical section of the transverse support plate 14 toward one side of the horizontal section of the transverse support plate 14. A tension spring is arranged between the two transverse support plates 14, and the tension spring drives the two transverse support plates 14 to move toward the positioning tube 9.

[0038] The longitudinal support plate 11 and the diagonal support plate 16 are controlled in sections by the axial movement and rotation of the regulating shaft 10, which is not only convenient for construction, but also avoids double positioning when the integral positioning structure is adopted, resulting in gaps at the top or side of the overlap. It is more suitable for corrugated plates with deformation, ensuring reliable sealing of the overlap of the corrugated plates.

[0039] In order to ensure that the overlapping parts of the corrugated plates are tightly fitted while fixing the upper roof panel group 6 or the lower roof panel group 7, the tightening components are located at the overlapping parts of the upper roof panel group 6 or the lower roof panel group 7 and the peak sections on both sides of the upper roof panel group 6 or the peak and valley sections on both sides of the lower roof panel group 7; the number of longitudinal tightening mechanisms and transverse tightening mechanisms is equal to the number of upper top beams 1 or bottom beams 2, and the longitudinal support plates 11 and the diagonal support plates 16 are both pushed to the upper top beam 1 or bottom beam 2 through the corrugated plates, and are limited at the stress-bearing points to avoid unnecessary deformation of the corrugated plates due to excessive tightening force.

[0040] The longitudinal support plates 11 and the diagonal support plates 16 of the tightening assembly are against the joints of the corrugated plates, which improves the strength of the joints of the corrugated plates. While positioning and fixing the upper roof panel group 6 and the lower roof panel group 7, the joints of the corrugated plates are forced to fit tightly through external force. Even if the corrugated plates are slightly deformed during production or transportation, it will not affect the installation and use, further ensuring the waterproof and thermal insulation properties.

[0041] Example 3 Based on the above embodiment, this embodiment further provides a construction method for a waterproof roof, including the following installation steps: S1, laying the lower roof panel group 7, overlapping and laying multiple corrugated panels on the bottom beam 2 to form the lower roof panel group 7, and applying sealant to the overlap of two adjacent corrugated panels; S2, laying the waterproof layer 8 at one time, bonding and laying the waterproof layer 8 on the upper surface of the lower roof panel group 7 laid in step S1; S3, laying the upper roof panel group 6, overlapping and laying multiple corrugated panels on the lower top beam 3 to form the upper roof panel group 6, and applying sealant to the overlap of two adjacent corrugated panels; S4, laying the waterproof layer 8 for the second time, bonding and laying the waterproof layer 8 on the upper surface or lower surface of the upper roof panel group 6 laid in step S3; S5. Install the tightening assembly. Install the assembled tightening assembly between the two end plates 5. S6, longitudinally tighten, axially move the control shaft 10, so that the two longitudinal support plates 11 synchronously move longitudinally in opposite directions, and the two longitudinal support plates 11 respectively press the top surface of the upper roof panel group 6 and the bottom surface of the lower roof panel group 7 against the upper top beam 1 and the bottom beam 2; S7, tighten the horizontal support, rotate the regulating shaft 10, so that the two horizontal support plates 14 are synchronously translated in opposite directions, and the diagonal support plates 16 at the upper and lower ends of the horizontal support plates 14 are against the peak section side of the upper roof panel group 6 and the peak and valley section side of the lower roof panel group 7. After tightening in place, the regulating shaft 10 is locked in the positioning tube 9 by the nut; S8, side seam sealing, apply sealant around the upper roof panel group 6 and the lower roof panel group 7 where they meet the side panels 4 and the end panels 5; When replacing the corrugated plate, the following maintenance steps are also included: Sa, unfasten, loosen the nuts between the positioning tube 9 and the regulating shaft 10 of the tightening assembly at the overlap of the corrugated plate on both sides to be replaced, rotate and pull the regulating shaft 10, so that the longitudinal support plate 11 and the diagonal support plate 16 are separated from the corrugated plate; Sb. Remove the corrugated plate, remove the upper plate 501 or lower plate 503 at one end, and pull out the corrugated plate that needs to be changed; Sc, replace the corrugated plate, insert the new corrugated plate into the upper roof panel group 6 or the lower roof panel group 7 from one end, and then install the removed upper plate 501 or lower plate 503; Sd, tighten, press and rotate the regulating shaft 10 at the overlap of both sides of the newly replaced corrugated plate, so that the longitudinal support plate 11 and the diagonal support plate 16 both tighten the corrugated plate, and rotate the nut to lock the regulating shaft 10 in the positioning tube 9.
